Missing default caddy configuration file?

ℹ️ Support
1

hi,
i got some jail “package” of nextcloud which is using caddy with lets encrypt. I need to remove lets encrypt; because i have other box with nginx that acts as reverse proxy. …

can anyone advice what is default caddy configuration in case i want to run nextcloud on port 80 and my nginx reverse proxy will add certificates and 443?

here is my current caddy conf but i dont think its good … at the moment it shows
root caddy 3559 7 tcp46 *:443 :
root caddy 3559 9 tcp46 *:80 :
but when i setup nginx reverse proxy on top of the caddy 443 it is permanently redirecting and it doesnt work.

thank you!
